Hi,
Thanks for the warm welcome !
Well, the boot scan definitely is not an issue to me, it works.
But what i was thinking is, IF one day my PC cannot boot up for whatever reason, and i suspect it is due to the virus, then i can use the boot diskette to scan/clean it.
Or another scenario will be, another PC(without antivirus software) was infected by virus, i can also use the generated emergency boot diskette to scan/clean it.
